[PATCH 5/6] Squashfs: fix f_pos check inget_dir_index_using_offset

From: Phillip Lougher
Date: Fri Mar 09 2012 - 22:11:37 EST



One off error in the f_pos check. If f_pos is 3 or less don't
bother reading the index because we're at the start of the
directory, and we obviously already know where that is on disk.

This eliminates an unnecessary read.
